 ## Troubleshooting
 C/C++ linting is not always straightforward. A few things to try when there's (almost) no linting information available:
 - Try to compile from the command line, and verify it works.
 - The linter might be missing some header files. They can be added with "include_dirs".
 - Sometimes clang fails to locate the C++ standard library headers.
 Assuming the compilation works when executed via command line, try to compile with `clang++ -v`.
-This will display all of the hidden flags clang uses. As a last resort, they can all be added as "extra_flags".
